Altough I use my WinXP PC daily I've just started to get an error message on log on to my User ID and several times each session. Message is "Generic Host Process for Win32 Services has encountered a problem and needs to close." On opening error report says "szAppName: svchost.exe szAppVer: 5.1.2600.0 szModName: ntdll.dll szModVer: 5.1.2600.1217 offset: 00044213." So far I've tried System Restore to a date before error notices began, run an up to date Norton Virus check, looked at MS Knowledgebase articles (that said a similar problem needed my HP printer drivers updated - so I did this), and looked at previous threads in this forum. However, no luck so far - can anyone help?
